An Intelligent PID Power System Controller Designed by Rule-based and Learning Control Algorithms

In this paper, an intelligent PID controller is proposed for power system voltage regulation and stability control, which is designed by rule-based and learning control algorithms. In the paper, application of fixed-parameter PID controller in a single-machine infinite- bus power system is studied by extensive nonlinear simulation, which verifies and leads to some interesting conclusions about robustness and control coordination between voltage regulation and stability control of power systems. Based on these conclusions,an intelligent PID controller is developed, main part of which are novel rule-based and learning control algorithms. Results of nonlinear simulation of the intelligent PID controller applied in the single-machine infinite-bus power system are presented in the paper as well.
